Blackburne Motorcycles and Engines

A Brief History of Blackburne

Blackburne engineers Cecil and Alec Burney built complete motorcycles and proprietory engines which were used in numerous English and Continental machines including:

Thomas Gillett was the founder of Burney & Blackburne.

The Blackburne factory was in Tongham near Farnham, Surrey.

Between 1923 and 1930, riders Norris, Beart and Jackson obtained considerable success with Blackburne KMA, KMB (racing engine) and KMC (sports engine) powered machines. (source)

The Burney motorcycle is related.

Blackburne Motorcycle
1921 - single
Today I ran across a 1921 Blackburne, equipped with a Corvette sidecar for sale. I had never heard of a Blackburne before. Is there a place that information on these is available?
It was on display next to a stop on a poker run I was on. It was in West Point, NE outside of Peterson's Autobody. I guess they restore old cars there and did so for the owner of the
Blackburne. The guy from Peterson's said the owner wanted $21,000 for it.
